I had 3 12w3d6 v1's sealed and they were decent, then i purchased a 12w7, ported it and I am very impressed. I can say the 12 sounds much better, but then again my 12's were sealed and a ported box for those suckers would not fit well in my trunk. I've heard good things about the 12w6's and Im sure it would sound nice ported, but if you want to go for the gusto, get the 12w7 ported. Im pretty sure the one 12w6 would get lound ported and 2 would be sick, just depends on your taste. If at all possible try to hear 12w6 ported and decide if its louder to you.
